[yocto] Timestamp error between zImage & uname-a [ Yocto-2.6.1 + Qemux86 ]

[AshishKumar Mishra]

Yes .
But this difference we expect in some minutes.


But what i am observing is ( attached snapshot ) :-
1) First Compilation around ( 4:10)
   bitbake cleanall + bitbake core-image-minimal
         uname-a                                            : Time shown is
4:24
         timestamp of files in deploy/images/    : Time shown is around 4:30


2) Second Compilation around ( 5:00)
   bitbake -c menuconfig virtual/kernel + bitbake -C deploy linux-yocto
         uname-a                                            : Time shown is
4:24
         timestamp of files in deploy/images/    : Time shown is around 5:25


2) Second Compilation around ( 5:00)
   bitbake -c menuconfig virtual/kernel + bitbake -C deploy linux-yocto
         uname-a                                            : Time shown is
4:24
         timestamp of files in deploy/images/    : Time shown is around 5:25

3) Third Compilation around ( 5:45)
   bitbake -c menuconfig virtual/kernel + bitbake -C deploy linux-yocto
         uname-a                                            : Time shown is
4:24
         timestamp of files in deploy/images/    : Time shown is around 6:05



So , time shown by "uname -a" is retains older value even though
i had compiled the linux multiple times .

Currently , only way i am able to bypass this behavior is to do bitbake -c
cleanall linux-yocto
before every compilation.

Thanks
